Acute myocardial infarction (AMI) is a chief cause of death worldwide. The best strategy to limit myocardial damage is to perform an early coronary reperfusion. However, despite reperfusion, the size of infarctions is many times large. Infarct size has been recently shown to be a strong predictor of future cardiovascular events and mortality. Therefore interventions aimed at reducing infarct size are the matter of intense research; but despite great efforts, no therapy has been shown to consistently limit infarct size.
